SPECIFICATION forming part of Letters Patent No. 666,660, dated January29, 1901.

Application filed June 12, 1900. 'ierial No. 20,032. No model.)

To all whom it Tim/y concern:

Be it known that I, ALFRED W. GABRIo, a citizen of the United States,residing at Hazleton, in the county of Lnzerne and State ofPennsylvania, have invented a new and useful Lubricating Trolley-WVheel,of which the following is a specification.

This invention relates to trolley-wheels in general, and moreparticularly to that class employed in overhead-trolley electric-railwaysystems, one object of the invention being to provide a constructionwherein the several working faces of the elements of the wheel will bethoroughly and automatically lubricated and in which, moreover, thelubricant will be supplied to the trolley-wire in such quantities as toprevent the adhesion of water thereto and the consequent formation ofice in cold weather.

Further objects and advantages of the invention will be evident from thefollowing description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a side elevation showing a trolley-arm provided with a wheelconstructed in accordance with the present invention. Fig. 2 is a planView of Fig. 1 with the trolley-wire omitted. Fig, 3 is a centraldiametrical section of the trolley-wheel, its shaft being shown inelevation. Fig. 4c is an edge view of the wheel, partly in section.

Referring now to the drawings, the trolleywheel is shown as mountedbetween the sides 5 and 6 of a frame, and which sides are pivotallymounted at their opposite ends upon ashaft or pin 7, which is passedthrough the arms 8 and 9 of a yoke or hasp at the end of the trolley-arm10. A spring-wire 11 is bent upon itself and its bight rests againstacrosspin 12, connecting the side plates 5 and 6, the wire beyond itsbight being wrapped around the pin 7 and having its ends resting againsta pin 13, engaged with the arms of the yoke. This spring-wire tends tohold the frameplates at an angle to the trolley-arm, and the pivotalmovement of the plates with respect to the yoke is limited by pins 15upon the yoke, which engage arc-shaped slots 16 in the frame-plates 5and 6, as shown.

The trolley-wheel is mounted rotata'bly upon a shaft 16, which isdisposed in alining perforations in the plates5 and 6, and is preventedfrom displacement by means of cotterpins 17, which are engaged'withperforations in the ends of the shaft.

The trolley-wheel consists of a central drum 20, midway of the ends ofwhich is formed an annular flange 21, having a grooved periphery 22,which forms the bottom of the peripheral groove of the completedtrolley-wheel, said flange being solid. Upon the central drum 20 and ateach side of the flange thereon is rotatably disposed a wheel-section 23and 24, respectively. Each of these sections is substantially disk-shaped, and they form the flanges of the complete wheel. Each of thesections 23 and 24 has its outer face slightly convex, while theperipheries thereof are concaved to conform to the curvature of theflange 21 of the drum 20, the inner faces of the sections 23 and 24being adapted to lie snugly against the outer faces of the flange 21. Ineach of the sections 23 and 24 is formed an annular chamber 25 and 26,respectively, communicating with which is a threaded perforation 27through the outer end or face of the section to permit filling thechamber therein, these perforations having plugs for closing them. Fromthe chamber within the section 23 leads a radial passage or duct 27 tothe shaft 16, through which the lubricant may be supplied to the shaftto lubricate the bearing between the drum 20 and the shaft, said ductbeing continued through the drum, as shown. Additional ducts 28 areformed through the inner faces of the sections 23 and 24 and adjacentthe outer edges thereof to permit the lubricant to pass to thecontacting faces of the flange 21 and the sections 23 and 24 and also topass between said sections and their contacting portions of the drum 20.The lubricant that passes out between the several elements is partlycarried by centrifugal and capillary action to the surface of the Wheelin the groove thereof, from which it is carried by contact to thetrolley-wire. By repeated trips over the wire the trolley acts to applya thin coating of the lubricant thereto, saving a large percentage ofthe wear upon the trolley and the wire and also preventing the formationof ice in cold weather. With this construction of wheel it will be seenthat no special form of trolley-arm is required, as the severalseparable parts thereof maybe disposed upon the usual wheel-axle.

To hold the parts of the wheel yieldably in mutual contact, aspring-plate 30 is riveted or otherwise secured to the inner side ofeach of the frame-plates 5 and 6 and has its opposite end bifurcated tostraddle the Wheel-axle, so that said plate may bear with its free endagainst the outer face of an adjacent outer section of the trolleyWheel. These two spring-plates thus hold the outer sections 23 and 24against the side faces of the flange 21, so that the parts of the wheelmay have lateral bodily movement.

It will of course be understood that in practice various modificationsof the construction shown maybe made and that any suitable materials andproportions may he used for the various parts without departing from thespirit of the invention.

What is claimed is- 1. A trolley-wheel comprising a hub having anannular flange provided with a peripheral groove, a disk disposedrotatably upon the hub at each side of the flange and containingoil-chambers, said disks having peripheral grooves at their inner sidescorresponding in curvature to the groove of the flange, and said diskshaving ducts leading from the oilchambers to the faces of the flange.

2. A trolley-wheel comprising a hub having an annular central flange, adisk rotatably mounted upon the hub at each side of the flgige andprojecting radially therebeyond, said disks lying against the end facesof the flange, said disks having ducts leading from the chambers to theend faces of the flange against which they contact, to supply oilthereto and therefrom to the periphery of the wheel to coat thetrolley-wire.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
